Step-by-step explanation:

i took the test hopefully is the right one.

Answer:

a° = 41°

b° = 139°

Step-by-step explanation:

a° = ∠DB

a° = 41°  

b° + 41° = 180°

b° = 180° - 41°

b° = 139

Answer:

We can think of this as a triangle rectangle.

We know that you eyes are 55ft above the ground, this can be one cathetus.

We also know that you see with an angle of depression of 50°, from this angle, our known cathetus would be the opposite cathetus.

Now we want to know how far is the object from you, this would be the hypotenuse of the triangle rectangle.

So we only know one angle and the opposite cathetus to this angle, then we can use the relation:

Sin(θ) = (opposite cathetus)/(hypotenuse)

Then if we use this equation, we will get:

Sin(50°) = 55ft/hypotenuse

hypotenuse = 55ft/sin(50°) = 71.8 ft

This means that the distance between you and the object is 71.8 ft.

Answer:

Answer:

a) 10.95

b) 76.65

Step-by-step explanation:

To find the unit price of Ben's video games, divide 43.80 by 4, which is equal to 10.95. So, the unit price is 10.95 at Ben's Game World.

Then, using the unit price we found earlier, multiply 10.95 by 7, which will gives us the cost of 7 games at Roberto's Electronics. You'll get 76.65. So, the cost of 7 games at Roberto's Electronics, using the same unit price at Ben's Game World, would be 76.65.

Hope this helps :)

Answer:

4. 21

5. 45

6. 22

Step-by-step explanation:

4. 6 + (2^4) - 1

   6 + (16) - 1

   22 - 1 = 21

5. (4 * 3²) + (18 - 9)

   (4 × 9) + (9)

   (36) + (9) = 45

6. 16 + (5² - 7) ÷ 3

PEMDAS tells us to do what's in Parentheses first

16 + ( 25 - 7) ÷ 3

16 + (18/3)

16 + 6 = 22

Answer:

15%

Step-by-step explanation:

15% of 15.95 is 2.39, which if we subtract from 15.95 we get 13.56

Could I please have Brainliest? Hope this helps! :)

Answer:

100%->15.95

1%->0.1595

15.95-13.56= 2.39

2.39÷0.1595

≈ 14.98% (corrected to 2 decimal places)

Answer:

[tex]\frac{382}{1000}[/tex]

Step-by-step explanation:

Answer:

191/500

Step-by-step explanation:

We have

0.382

0.382 = 382/1,000

Simply 191/500 therefore answer is 191/500. How I got that was I divided .382/1,000 by 2 numerator and denominator.

Hope this helps

Answer:

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5)

Step-by-step explanation:

Given the x- intercepts are x = 3 and x = - 5 then the corresponding factors are

(x - 3) and (x + 5)

The equation is the the product of the factors, that is

y = a(x - 3)(x + 5)  ← a is a multiplier

To find a substitute (- 1, 8) into the equation

8 = a(- 1 - 3)(- 1 + 5) = a(- 4)(4) = - 16a ( divide both sides by - 16 )

- [tex]\frac{1}{2}[/tex] = a

Then

y = - [tex]\frac{1}{2}[/tex] (x - 3)(x + 5) ← in factored form

Answer:

I believe what your asking me to do is put the y value back into the equation and solve for x. If so x=6 or x=(5/9) SEE BELOW

Step-by-step explanation:

y=(2/3)x-1 , y=3

3=(2/3)x-1

4=(2/3)x

x=6

OR

y=2/(3x-1)

x=(5/9)

Answer:B

Step-by-step explanation:AP3X

=================================================================

Work Shown:

The diagram shows that JK = 12 and GF = 2.5*(JK) = 2.5*12 = 30

The midsegment HL will be the average of the two lengths it is parallel to.

We'll add up the values and then cut the result in half

HL = (JK+GF)/2

HL = (12+30)/2

HL = 42/2

HL = 21

Answer:

multiply each side by -5

Answer:

[tex]\frac{9}{20}[/tex] [tex]miles^{2}[/tex]

Step-by-step explanation:

To find the area of a rectangle, use the formula A = l*w, where l is the length and w is the width.

A = [tex]\frac{9}{10}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{9}{20}[/tex] [tex]miles^{2}[/tex]

Answer:

XT and XW

Step-by-step explanation:

They are indicated congruent by the congruency marks on each.

Answer:

No Solution.

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

if LA = AK then the triangle is isosceles

if the two triangles are similar then we can use this proportion to find LA:

8/12 = 6/LA

cross-multiply:

8·LA = 72

LA = 9

Answer:

∠x = 16°

Step-by-step explanation:

∠x = 180° - (180° - 16°) = 16°

Answer:

16° because alternative exterior angles are equal

Answer: what’s the question?

Step-by-step explanation:

Answer: The selling price will be $1.68  

Step-by-step explanation:

If the magazine is marked-up by 12% , then you will multiply 12% by the amount of money then add it to the same amount of money.

1.50 * 12% = 0.18

1.50 + 0.18 = 1.68

Answer:

They can have infineyely many solutions :)

Answer:

Well Circumference = πr^2, but I don't know what you're asking for?

Answer:

Let be "x" the cost in dollars of a hamburger and "y" the cost in dollars of a soft drink.

The cost of 4 hamburguers can be represented with this expression:

4x4x

And the cost of 6 soft drinks  can be represented with this expression:

6y6y

Since the total cost for 4 hamburgers and 6 soft drinks is $34, you can write the following equation:

4x+6y=344x+6y=34   [Equation 1]

 The following expression represents the the cost of 3 soft drinks:

3y3y

According to the information given in the exercise, the total cost for 4 hamburgers and 3 soft drinks is $25. Then, the equation that represents this is:

4x+3y=254x+3y=25 [Equation 2]

Therefore, the Equation 1 and the Equation 2 can be used to determine the price of a hamburger and the price of a soft drink

Answer:

3x + 6y = 27

3x + 3y = 18

x = $3, y = $3

Step-by-step explanation:

I will solve by using the elimination method.

3x + 6y = 27

3x + 3y = 18

Subtract top equation by bottom.

3x + 6y = 27

- (3x + 3y = 18)

_____________

  0 +  3y  =  9

3y = 9

y = 3

Plug y in for three

3x + 6*3 = 27

3x + 18 = 27

3x = 9

x = 3

So, your solution is x = $3, y = $3
